Simultaneous and Segmental Measuring
The AngE Pro 8 is an 8-channel pulse oscillography device with optional additional ECG-trigger. It offers measurement methods for the simultaneous and segmental measuring, which leads to a better comparison of the vessels in the extremities and an improved Doppler-Index calculation.
The pulse waves are recorded at different cuff pressures and the mean arterial pressure is determined by the maximum amplitude. The comparison of the mean arterial pressure values leads to an automatic calculated oABI (oscillometric Ankle Brachial Index).
Additionally, the AngE has a built-in ECG-trigger that works simultaneously to the cuff-measurements, allowing the determination of the pulse wave runtime as well as pulse wave velocity.
The alternative solution to ABI
These days, even in our health care system, cost-effective operation is a necessity. The AngE Pro 8 has been developed to obtain the diagnosis of a peripheral arterial occlusive disease quickly, reliably, with cost-effectiveness and without stress for the patient. Therefore, the classic, more time consuming and hard to document ABI measurement is a relic from the past.
Using the oscillometric principle developed by Gesenius and Keller, the pulse waves are recorded at different cuff pressures. The mean arterial pressure is determined by the maximum amplitude. The comparison of the mean arterial pressure leads to a result similar to the ABI.
The system is able to record the pulse waves at fingers and toes, thigh and lower leg as well as ankle and wrist at 8 channels. Due to the simultaneous measurement, there is no time difference between the measurements on the single extremities as with the ABI measurement. This delay between the individual determinations of blood pressure values leads to an inaccuracy which is avoided by the AngE. In addition, the simultaneous recording allows the comparison of time values between the limbs.
Patients suffering from diabetes often have very calcified vessels (media sclerosis), which cannot be compressed. Therefore, the ABI results are unusable.
Using the finger and toe measurement of the AngE, reliable results can be obtained, because the media sclerosis affects the toes only in less than 1% of such patients. Measuring this way, even with patients suffering from media sclerosis, a fast and consistent diagnosis is possible. This early detection of pAOD avoids lots of complications for the patient.
Simultaneous Synchronic Oscillography
The AngE Pro 8 lets you perform a simultaneous synchronic oscillography at 8 measuring points. This prevents a falsification of the results through blood pressure variability. Comparing the simultaneously recorded extremities, it also allows you to recognize time deviations in the pulse wave.
Furthermore, the 8 cuffs applied to the patient allow a much better localization of a disease. The results get evaluated automatically. Values such as pulse wave velocity, ABI (Ankle-Brachial-Index) and the pulse waveform will be calculated immediately by your AngE Pro 8.
The AngE Pro 8 lets you launch an 8-channel segmental oscillography. The measurement works by simply attaching the patient to the cuffs. Then the cuffs are inflated and measured one by one. Each channel with its pulse wave will be saved and evaluated after the measurement. This allows the software to automatically localize occlusions. Furthermore, the curve-form, the pulse wave velocity and the ABI (Ankle-Brachial-Index) will be evaluated automatically.
With the AngE Pro 8, you can easily start a simultaneous 8-channel Morbus Raynaud diagnostic. Due to the possibility of measuring 4 fingers on each hand at the same time, the screening can be performed in a short time. There is also the possibility to provoke the vein-system through putting the hands into cold or warm water during the measurement. This allows you to evaluate the vein system's reaction under different conditions.
One of the AngE Pro 8's best improvements is the better-displayed pulse wave. Using better pressure sensors and an elaborated filter algorithm, the pulse wave is more sensitive and detailed than before. This lets the examiner recognize even smallest spikes.
The AngE Pro 8 provides a multitude of additional parameters compared to the ABI measurement. Where the ABI only provides pressure values of the limbs, AngE records the pulse wave which allows obtaining a detailed pulse wave analysis. Parameters such as rise time, amplitude and the optical appearance of the pulse wave can be evaluated.
The calculation of RI(reflection index) and SI(stiffness index) allow the identification of patients with a high vascular risk by the inclusion of the dicrotic wave into the measurement. With medicamentous provocation, the endothelial function can be examined.
With the recording of the ECG signal, it's possible to use the R-wave to obtain a trigger point, thus allowing the measurement and calculation of pulse wave runtime and pulse wave velocity. These parameters increase in their importance according to the evaluation of the state of the vessels e.g. in clinical monitoring of patients suffering from hypertension.
The AngE Pro 8 is shipped with two electrode clamps in order to minimize the effort involved in the measurement. The electrodes just need to be placed on the patient's wrists.
